					                  Non-local correlation between human
                 neural networks on printed circuit board
The Penrose-Hameroff model [1][2] identifies microtubules inside neurons as responsible
for quantum effects in brain. Several experiments seem to indicate that EPR-like
correlations are possible at the biological level[3][4][5] and one has been proposed at the
neuronal level [6].
In the past year , an intensive experimental work on this subject has been done at the
Dept of Information Technologies of the University of Milan, in collaboration with the Stem
Cells Research Institute- DIBIT S. Raffaele , Milan, Italy [7] . Our experimental setup is
constituted by two separated and completely shielded basins of human neurons adhering
to printed circuit boards, connected to a PC by means of a signal acquisition card.
Our main experimental result is that, under stimulation of one culture by means of a 630
nm laser beam at 300 ms, the cross-correlation between the two cultures grows up at
maximum levels. Moreover, the structure of the autocorrelation function is clearly the same
for both signals. Despite the difference in mean level and amplitude of oscillation, both
signals seem to share the same (nonlinear) production mechanism.
Several others experiments , also involving super-position of light stimulation, have been
and will be performed in the future to get a clear picture and possible hints to understand
the deep physical reasons of this non-local correlations.
Despite at this level of understanding it is impossible to tell if the origin of this non-locality
is a genuine quantum effect, our experimental data seem to strongly suggest that
biological systems present non-local properties not explainable by classical models.
